SOME INTERESTING AEROMAGNETIC ANOMALIES OF THE WESTERN DESERT, IRAQ

Abstract

Detailed gravity measurements for some of the relatively impressive short wave magnetic anomalies of the westernmost part of the Western Desert indicate that these anomalies are associated with fracture or fault zones present within the sedimentary cover. One of these anomalies is Al-Waleed anomaly zone present at the cross of regionally extended fault zones over nearly circular cone anomaly. The cone anomaly interpreted as igneous chamber present at a depth of about 2.5 Km within the level of Silurian hot shale. Another anomaly zone (East Traibil anomaly) is followed up by gravity measurements for about 20 Km and shows good correlation with the location of the known regional Amij – Samarra Fault Zone. Nehadain Anomaly Zone, which is with arcuate shape, extends for more than 50 Km. The anomaly source is proved to be a gas trap in its Jordanian part. The aim of the work is to introduce such anomalies for farther studies to clarify their economic importance.
